Petroleum products are materials made from crude oil as it is processed in oil refineries. Petroleum products are often complex mixtures with them being several classes of fuel. Refineries can produce different shares of petroleum products, the largest share is called an energy carrier which can be blended to give gasoline, jet fuel, diesel fuel, heating oil and more

Petroleum products are materials made from crude oil as it is processed in oil refineries. Petroleum products are often complex mixtures with them being several classes of fuel. Refineries can produce different shares of petroleum products, the largest share is called an energy carrier which can be blended to give gasoline, jet fuel, diesel fuel, heating oil and heavier fuel oils. Heavier and less volatile can be used to produce asphalt, tar and heavy oil. Some refineries also produce other gasses and chemicals that can be used to produce plastics.
